Kekkai Onmyouji

Saya is an Onmyouji, and is also a Kekkai user, the one and only person powerful enough to generate a Kekkai to beat Matobe Seiji. Now, Seiji meets Saya on the way to his meeting, and finds her utterly fascinating. He meets her again, and there, she unleashes her Kekkai powers and helped him to vanquish his enemy, the one that is after his eye. MatobaxOC
